GLOBE-VALVE.

Specification of Letters Patent.

Patented May 2, 1911.

Application filed April 15, 1909, Serial No. 490,034. Renewed September30, 1910. Serial No. 584,758.

To all whom t may concern.'

Be it known that I, JOHN L. Sci-mona, citizen of the United States,residing at Hopkinsville, in the county of Christ-ian and State ofKentucky, have invented certain new and useful Improvements in Globe-Valves, of which the following is a specification. i

This invention relates to improvements in .the style of valve describedin my cordinate application for patent, the essential differencesbetween the valve disclosed in said application and the one hereinafterdescribed being that in the former one valveseat is adapted to thevalve-head irrespective of the relative position of the head, while inthe present device, two seats are provided and means are disclosed forclosing one of the seat openings when the valve is changed from theangle-form to the straightway style, and vice-versa.

One of the objects of the hereinafter described improvements is toprovide an interchangeable form of valve in which the seat can bereadily renewed, and to so connect the valve-stem and valve proper thatthe latter will not necessarily turn with the turning of the stem inadjusting the valve on its seat.

In the accompanying drawing :-Figure 1 is a sectional view of mycomplete improved valve on a median line, Fig. 2 is a detail of the ballvalve which I use, and Fig. 3 shows a modified form of seat for theball-valve.

Referring to the details of the drawing 5 represents a valve body ofglobular form from which extend three necks 6 of uniform size and eachhaving corresponding internal threads 7 Extending across the interior ofthe body is a partition or bridge 8 which is in the form of aright-angle, one side or wall of which is parallel with the horizontalnecks, and the other is parallel with the vertical neck. In each ofthese partition walls is an opening provided with internal annularthreads 9 to provide a seat for the ballvalve 17 to be described. Whenone of the seat openings is not in use it will be closed by the nut 9awhich is screwed into the female threads 9.

In Fig. 3 I have shown a threaded collar 4t having its inner facebeveled, which may be screwed into the threaded opening 9'and thllisprovide a renewable seat for the ballva ve.

10 represents a bonnet which is formed with a threaded extension 10aadapted to be screwed into any of the necks or extensions G. The bonnetis also cast with an externally and internally threaded neck 11, theouter threads to receive the cap nut 12, and the inner threads toreceive the threaded valve-stem 14.

The valve proper 17 is spherical and recessed and threaded as at 16 toreceive the collar 15 which fits loosely over the lower end of thevalve-stem. The ball-valve is also provided with a recess countersunk ifrom the threaded recess, to receive loosely the flanged extremity 13aof the valve-stem. This construction and arrangement permits theeffective union between the valve and its stem, without causing thevalve to rotate when the stem is turned in the operation of the valve.

As shown in full lines in the drawing, the device is arranged as astraightway valve, the plug 9a being screwed into the openings in thevertical portion of the partition or bridge 8. In dotted lines I haveshown the bonnet screwed into one of the horizont-al extensions 6, andthe ball-valve seated in the opening in the vertical wall. When soarranged, it will be understood that the plug 9a will be transferred tothe opening in the horizontal wall 8, and thus an angle-valve will beformed.

Having thus described my invention what I claim, is

1. A valve comprising a body portion having threaded radial extensionsof uniform bore, a bridge extending across the said body and having twowalls at an angle to each other, each of said walls having a threadedvalve-seat therein, a bonnet adapted to be screwed into any of saidextensions, and a valve proper having a stem passing through saidbonnet.

2. A valve structure comprising a body having a plurality of tubularextensions, a bridge extending across the body and having threadedvalve-seats arranged therein at right-angles to each other, andintersecting the vertical and horizontal axes of the body, a bonnetadapted to fit said extensions, a valve having a stem adjustable in saidbonnet, and detachable means for closing one of the valve-seats when theother is in use, said means adapted to engage the threads in thevalve-seats.

3. A Valve-structure comprising a body having a plurality of tubularextensions and a bridge extending transversely of said body and having aplurality of threaded valveseat openings therein, a collar adapted to bescrewed into said openings and to furnish a valve-seat, a plug adaptedto be screwed into said openings and to effect a closure there for, aValve adapted to be seated on said seat, and a bonnet adapted to fitsaid extensions.

4. A valve-structure comprising a. body having a plurality of tubularextensions, and a bridge extending across the body and having threadedvalve seats arranged therein at right angles to each other andintersecting the vertical and horizontal axes of the body.

5. A valve-structure comprising a body having a plurality of tubularextensions, a bridge extending across the body and having threaded valveseats arranged therein at 4right angles to cach other and intersectingthe vertical and horizontal axes of the body, a bonnet adapted to itsuch extensions, a valve having a stein adjustable in said bonnet, and athreaded plug designed to close one of the Valve seats when the other isin use thereon and adapted to engage the threads in the said valveseats.

In testimony whereof I affix iny signature in the presence of twoWitnesses.
